ABSTRACT:
A profiled clamp with at least one profiled segment which extend successively in the circumferential direction of the clamp and are clamped by means of at least one clamping device. The profiled segments have a profile which in cross-section is essentially inversely trough-shaped or cup-shaped. When the clamp is clamped, flanges which are provided at the ends of two pipes to be connected by the clamp are pressed toward each other between diverging side walls of the profiled segments. Gaps with a bottom each are provided between adjacent profiled segments. In each gap is provided a resilient metal strip at a distance from the bottom of the gap which is greater than the thickness of the bottom of the profiled segments, wherein the metal strip extends transversely of the plane of the clamp, and wherein the metal strip is mounted through lateral arms of the metal strip at the bottom of the gap.
